Hi I just can't figure out why my velocity numbers are allways alot lower than they should be according to the reloading data, for example 223 rem 28gr varget 40 gr vmax 3100 fps 27 gr varget 50 sierra's 3000 fps, this is the kicker white box bulk 55gr 3400fps!!! this goes for all my loads all the way up to 300 win mag and every thing in between, the groupings are fine but the low numbers baffle me they are all several hundred fps down from factory loaded rounds. all my rifles are stevens 200 with 22 inch barrels except the 300 win with a 24 inch tube.
thanks Dean
